Optimization and Construction of Human Insulin-like Growth Factor 1 Gene related to human health
Background and aims: Laron syndrome is a disease that treated by Insulin-like Growth Factor 1 (IGF-1). This protein is a single chain and has three disulfide bonds. People with Laron syndrome have low rates of cancer and diabetes, although they appear to be at increased risk of casual death due to their stature. IGF-1 is synthesized by many tissues and is secreted from liver as an endocrine hor...
متن کاملProduction and functional characterization of human insulin-like growth factor 1
Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...
متن کاملThe Insulin-like Growth Factor-1 (G>A) and 5,10-methylenetetrahydrofolate Reductase (C677T) Gene Variants and the Serum Levels of Insulin-like Growth Factor-1, Insulin, and Homeostasis Model Assessment in Patients with Acne Vulgaris
Background & Objective: To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods: In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphis...
متن کاملInsulin-like Growth Factor Receptors
There are two types of insulin-like growth factor (IGF) receptors. The type I receptor generally binds IGF-I more tightly than IGF-II and also interacts weakly with insulin. The type II receptor prefers IGF-II over IGF-I and does not recognize insulin. The type I receptor is made up of an alpha binding subunit (Mr 130000) and a beta subunit (Mr 95 000) probably organized as a heterotetramer (Oi...
متن کاملThe role of insulin-like growth factor 1 and insulin-like growth factor binding protein 3 in human esophageal cancer.
BACKGROUND Insulin-like growth factors (1GF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) play important roles in cell growth and differentiation. The aim of this work was to investigate the roles of IGF-1 and IGFBP-3 in esophageal cancer. MATERIALS AND METHODS We examined the circulating IGF-1 and IGFBP-3 concentration in 18 healthy controls and 66 esophageal cancer patients ...
